As we discovered in the Plains of Eidolon the mod sets are mods which grants you an extra bonus when you use them simultaneously. Each mod of the set can be installed in your Warframes, weapons and companions depending on their type generating a synergy.
This synergy is represented with a bar divided in segment you can see in the mods. Each mod is divided in two parts, the first one is the individual bonus each mod has, and in the bottom part is located the synergy bonus.
These mods can be obtained when you successfully complete the Eudico Bounties in Fortuna and the ones offered by the Solaris agents in the Orb Vallis.
Synth Mods Set
The Synth Mod Set is used in Secondary Weapons, Sentinels and Warframes, being its maximum synergy effect 20% recharge of the Primary or Secondary weapons when they are sheathed. Each mod of the set adds a 5% to this synergy effect.
Mecha Mods Set
The Meca Mod Set is used on Kubrows and Warframes, being its maximum synergy effect for the Kubrow: each 15 seconds the Kubrow will mark an enemy for 12 seconds, killing this enemy will apply the Status Effects to all enemies in 30 meter radius.
Tek Mods Set
The Tek Mod Set is used on Kavats, Warframes and Melee Weapons, being its maximum synergy effect for the Kavats: The Kavat creates a 10 meter area each 15 seconds which causes 50 damage per second during 8 seconds.
And that’s all we can say about the Synth, Meka and Tek mod sets. Remember that you can obtain them completing Bounties in Fortuna. As always, if you see any mistake or missing information let us know through the comments below.
